B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

### Step-by-Step Solution:

1. **Definition of Tracheophytes**:
- Tracheophytes are also known as vascular plants. They are characterized by the presence of vascular tissues, which include xylem and phloem. These tissues are essential for the transportation of water, nutrients, and food throughout the plant.

2. **Types of Tracheophytes**:
- Tracheophytes are classified into three main groups:
- **Pteridophytes**: These are non-seed vascular plants, which include ferns and horsetails. They reproduce via spores.
- **Gymnosperms**: These are seed-producing plants that do not form flowers or fruits. Examples include conifers like pine trees.
- **Angiosperms**: These are flowering plants that produce seeds enclosed within a fruit. They are the most diverse group of plants.

3. **Additional Information**:
- While the question mentions three types of tracheophytes, it is important to note that there are other groups, such as club mosses, which are also considered vascular plants but are often not included in the primary three categories.

4. **Conclusion**:
- In summary, tracheophytes are vascular plants that include pteridophytes, gymnosperms, and angiosperms. They are distinguished by their vascular tissues, which allow them to thrive in various environments.
